Figs. :l and 4:, and a movzihle gripping member having the form.

of the stationary gripping member of Figs.

3 and 4:, as hereinafter iore fully described.

,Siiriilsr numerals (mil letters refer to siniilar parts throughout the several views.

11 is the base; 152 is stationary column, which may be secured to the base in any suitable moi-hirer. i3 is e i'iar e, secured to the upper end said column-12, which. flange is shown in Fig. i as connected to thehoi; ii of the stationary gripping 1hemher by means of the ears H or soidbox 1 and the bolts l6 o. movable column shown inclosecl h ssicl stationery column 12 through port of the leiigrtl'i of said mow able column i6, which is out of contact with the inside oi? said, coiumn '12.

17, 17 are movable keys of ihe stationary gripping member, which keys 1'? are shown in Figs. 3 zinci 8 as having ilieir backs in slicling contact Wifih the inside oi the box 1-ion the inclined cmis thereof; che inner edges of said keys 1"? shown having grooves or roccweys, containing the rolling members 18 on both sides of said column 16, which rollingmembers may be either cylinclricol as shown in i, or spherical, desired. The books of the grooves or racevsys, in which said members i8 lire locziteol, are shown as inclined to seici column 16, which is shown in 1 end 2 square in cros scclion, but which may be oi any other suitable shape. 19, 19 are trip roos, shown in i oncl'l'h as co'o iiecteol each at its upper cool to one oi said keys 1.? by means of the studs 20 coil at its lower and to the lever 21 by means of the pin 29;; saici lever 2-1 is shown in Fig. 5 as pivoizslly concocted to the base 11 by means of the pin 23.

24 is the box of the movable gripping member, which is shown in Fig. 3 as extensibly connected to soicl box Li by means 0i 3 hooked on at their upper ends to the rings, formecl {it the coils of the lugs iii of ssio. box 24;, and at their lower ends to similar rings 14;

Milli of said box 14. 24 are bosses shown in Fi 27, 27 are movable keys of the movable gripping member, which keys are shown in Figs. 4 and 8 as having their backs in sliding contact with the inside of said box 2 1 on the inclinedends thereof; the inner edges of said keys 27 are shown as having grooves or raceways, similar to those of the keys 17, and rolling members-28 in said grooves or raceways on both sides of said column 16.

29, 29' are connecting rods, shown in Figs. 3, 4 and 5 as'secured at their upper ends to said keys 27, by means of the studs 30, and at their lower ends to the lever 31 by means of the pin 32; said lever 31 is shown in Fig. 3 as pivotally connected to the base 11 by means of the; pin 33. 3 1 is a'spring, which is shown in Fig. 3 as connecting said lever 31 to a beam 35, secured to the column 12 on the outside thereof. 36 'is a similar spring shown in Fig. 5 as connecting the lever21 to the beam 37, which is similar to the beam 35. The beams 35 and 37 may be connected to said column 12 sufliciently high to allow a suitable length for each of said springs 34: and 36.-

The springs 34: and 36 cause the levers 31 and 21 respectively to pull on the connecting rods 29 and tripping rods 19 respectively. Said tripping rods 19 are. transmit ting the tension to the keys 17 of the stationary gripping member, which keys 17 are thereby jammed in between the inclined ends of the box 14 and the'rolling members 18, which are'thereby pressed against said column 16; the resistance to sliding of said column 16 between said rolling members 18 is increased as the component of the pressure upon its surface, normally thereto, increases, until this resistance to sliding is greater than the resistance to rolling, rising in proportion to the normal pressure;

hence, at a certain intensity of normal pres-Z sure, the column 16 will not slide any more, and, as it starts to roll down the members 18 are jammed down the inclined back of the grooves or raceways in the keys, thereby raising the normal pressure on said column I 16 to such an intensity that the resistance to rolling becomes greater than the load on said column 16, which load is thereby supported inposition; the magnitude of this load is only limited by the resistance oi. the rolling members 18 to crushing.

The keys 27 of the movable gripping member are shown in Fig. 4 as resting on the box 14 oi the stationary gripping member, and the lower end of said box 2% of the movable gripping member is shown in Fig.

r 3 as not quite touching the heads of the keys which is not 17; the box 21 is then jammed on to the keys 27 by the springs 25, 26, the tension of which springs produces the same cll'cct on the roll iiig members 28, 28 as the tension oi? the spring 36 does on the rolling members 18,

as above described.

\Vlien not interfered with, both gripping members are serving as supports for any load carried by the column 1( thc upper end of which is shown as broken away.

VVheu it is desired to raise the column 16, the pedal 31 ot' the lever 31 is stopped upon, thereby raising the connecting rods 25), 25) against the tension of the spring 34-; the

keys 27, shown in Figs. 3 and at, are thcrcl 1y vmoved upwardly, raising with them tho.

causes the key 17, shown in Fig. 3, with the rolling members 18 to act as hercinhcl'orc described, and the column 1.6 is instantly seized by the stationary gripping member and held fast. The spring 34 also acts upon 'the lever 31, which in turn pulls the ronnecting rods 29, 29 downwardly, thereby bringing the keys 27, 27 down and on to the upper end of the box 14, on which they resume their position, as shown in Fig. 4-; the box 2 1 is then brought down .by its own weight, aided by the tension of the springs 25, 26, which jam said box 24 on to said keys 27, 27, thereby causing them to press on said rolling members 28, 28; said movable gripping member thereby also seiiccs said column 16 and holds it fast; and the operation of raising the column 16 a short distance may be repeated any desired number of times.

To release the column 16, and to allow it to fall, the pedal otthelever 21 is stopped upon, therebycausing the tripping rods 19 to lift the keys 17, 17, shown in Fig. 8, thereby releasing the rolling members 18 of the stationary grippingmember; the heads 17 of the keys 17, when lifted, also act on the bosses 24: of the box 2%,thereby lifting said box 2 1 off the keys 27, which are shown in Fig. 3 as kept down by the spring, 34-, acting through the lever 21 and connecting rods 29; this separation. of the box 2'1 from the keys 27 causes the upper gripping member also to release the column 16.

In Fig. 3 a clcarancc is shown between the heads of the keys 17 and the be... 24:; this clearance is provided to insure the connected toveach of said footlevers and 5 keys in each gripping member, raceways in position after each displacement thereof.
